rose about one degree fahrenheit during the 20th century. it is human activity that has caused this global warming. all scientists subscribe to the view that the increase in the earths temperature is due to the burning of fossil fuels. some byproducts of this process are called greenhouse gases，which trap heat and warm the earth. without the greenhouse effect，the earth would be cooler than it is. but scientists dont agree with each other on the effects of global warming. some think it will be a disaster，but some others think its a good thing and we can do nothing to prevent the trend. by reading the second passage，we also know some easy and effective measures we can take to deal with global warming.from this unit you have also learned：some useful
